Most shock absorbers use a hydraulic system to control the flow of oil or gas within the unit. When a vehicle encounters a bump, the shock absorber piston moves within the cylinder, forcing the hydraulic fluid to pass through small openings or valves. This process converts the kinetic energy of the suspension movement into thermal energy, which is then dissipated into the environment as heat. The controlled resistance provided by the shock absorber helps keep the vehicle's chassis stable and prevents excessive bouncing or oscillations.

2. Brake Fluid Inspection: Inspect the color and clarity of the brake fluid. Clean brake fluid should be almost clear with a slight yellow tint. If the fluid appears dark or murky, it may be time for a brake fluid flush.

What are Wheel Bearings?
Wheel bearings are small steel balls or rollers that are encased in a metal ring. They are designed to reduce friction and support the weight of the vehicle, allowing the wheels to spin freely. There are typically two wheel bearings in each wheel assembly - an inner bearing and an outer bearing. Some modern vehicles may have integrated hub units that include the bearing assembly, making replacement easier.

One of the key roles of a strut bearing is to support the weight of the vehicle and absorb the shocks and vibrations that occur while driving. It helps to maintain proper alignment of the wheels and allows for smooth steering and handling. By providing a pivot point for the strut assembly, the strut bearing also allows the suspension system to move up and down in response to road irregularities, ensuring a stable and controlled ride.

Exhaust manifolds are typically made of cast iron, stainless steel, or in some cases, ceramic coating. The choice of material depends on factors such as cost, durability, and performance requirements. Cast iron is a common material used for exhaust manifolds due to its ability to withstand high temperatures and resist corrosion. Stainless steel is another popular choice as it offers better resistance to heat and corrosion compared to cast iron.

Shock absorbers are designed to dampen the motion of the vehicle's springs as they compress and rebound in response to bumps, potholes, or other irregularities on the road. By absorbing and dissipating the kinetic energy created by the suspension movement, shock absorbers help maintain consistent contact between the tires and the road surface, improving traction, handling, and braking performance.

Maintenance Tips for Headlamp Bulbs:
1. Regularly inspect your headlamp bulbs for any signs of damage, discoloration, or flickering. Replace bulbs that are dim or burnt out to maintain proper lighting on the road.

Over time, strut bearings can wear out or become damaged due to constant exposure to road conditions, extreme temperatures, and general wear and tear. Common signs of a failing strut bearing include knocking or clunking noises when driving over bumps, uneven tire wear, steering instability, and increased vibration in the steering wheel.

- Excessive bouncing or bouncing after hitting a bump.
- Uneven tire wear or cupping.
- Increased body roll, pitch, Aftermarket ECU Upgrades or nose dive during braking.
- Oily residue on the shock absorber casing.
- Knocking or clunking noises from the suspension.

Introduction:
Headlamp bulbs are an essential component of any vehicle's lighting system, providing illumination for night driving, inclement weather, and improving visibility on the road. Understanding the different types of headlamp bulbs available, their features, and how to properly maintain them is important for all drivers. In this article, we will shed light on headlamp bulbs to help you make informed choices for your vehicle.

In conclusion, brake fluid is a vital component of your vehicle's braking system, and proper maintenance is key to ensuring safe and efficient operation. By understanding the functions of brake fluid, its importance in maintaining braking performance, and following the tips provided, you can help keep your brakes in top condition and ensure your safety on the road.

When to Replace Wheel Bearings:
If you suspect that your wheel bearings are failing, it is best to have them inspected by a professional mechanic. Wheel bearings that are worn out or damaged should be replaced immediately to prevent further damage to the vehicle and ensure safe operation. Replacing wheel bearings is not a DIY job and should be done by a qualified technician.

4. **Enhanced Safety**: In emergency situations or sudden maneuvers, effective shock absorbers contribute to the vehicle's ability to maintain traction and stability. This can help prevent skidding, loss of control, and potential accidents, making shock absorbers a key safety feature in any vehicle.

3. Brake Fluid Flush: It is recommended to flush and replace brake fluid every 2-3 years, or as specified in your vehicle's maintenance schedule. This process involves removing all the old fluid and replacing it with fresh fluid to ensure proper braking performance.
